Specification of Letters Patent.

Patented Aug. 29, 1916.

Application filed May 12, 1916. Serial No. 97,210.

T 0 all whom it may concern:

Be it known that I, YOKIOHI KINosHrrA, a subject of the Emperor of Japan, residing at Boston, in the county of Suffolk, State of Massachusetts, have made a certain new and useful Invention in Hinge Structures for Screen-Sections, of which the following is a specification.

This invention relates to hinge structures for screen sections and like purposes.

The object of the invention is to provide a hinge structure of the nature referred to which is simple, strong, durable, efficient and inexpensive.

A further object is to provide a hinge structure of the nature referred to wherein the hinge connections are neatly concealed.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawing, and finally pointed out in the appended claims.

In the drawing :Figure 1 is a broken view in elevation showing the abutting edges of screen sections connected by a hinge structure of my invention, the screen sections being shown in alined relation. Fig. 2 is a similar view in perspective, parts broken out, showing the screen sections in angularly displaced relation to each other. Fig. 3, is a similar view in section on the line 3, 3, Fig. 2. Fig. 1 is a similar view on the line 4:, 1, Fig. 2. Fig. 5 is a view showing the screen sections in alinement but abnormally displaced from each other to show the relation of the hinge connecting straps. Fig. 6 is a perspective view showing one of the hinge straps and the retaining strips therefor detached from the screen sections. Fig. 7 is a longitudinal sectional view of the same. Fig. 8 is a view similar to Figs. 3 and 4, showing a slightly modified form of retaining strips employed in connection with my invention.

The same part is designated by the same reference numeral throughout the several views.

Reference numerals 9, 10, designate, respectively adjacent sections of a screen to be connected together by a hinge connection. In the opposed edge surfaces of the screen sections are formed longitudinally extending grooves 12, 13, which, in the particular form shown, are V-shaped in cross section, and form seats to receive retaining strips 1 1, 15, of cooperating shape in cross section. These retaining strips 141, 15, may be secured in place by any suitable means. I have shown removable screws 16, 17, for this purpose, said screws respectively passing through the strips and into the adjacent screen section. Hinge straps are shown at 18, 19. Each strap has one edge 20, thereof clamped between one side or face of a retaining strip as l l, and the opposed wall surface of its seat in the groove 12, and then is passed transversely across the end edges of the screen sections and between the outer faces of the retaining strips, and the other edge 21, thereof clamped between the diagonally opposite side or face of the other retaining strip 15, and the opposed wall surfaces of its seat in the groove 18, of the other screen section, said edges 20, 21, if desired, being secured in any suitable or convenient manner to the side surfaces of the retaining strips referred to, as, for instance, by means of fasteners 22. In practice I employ the hinge straps 18, 19, connected up in successively alternating relation throughout the length of the hinge structure. That is, the edge of one is clamped between one side or face of a retaining strip and its opposing wall surface of the screen section, while the corresponding edge of the next strap is clamped between the other side or face of the same retaining strip and its opposed wall sur faces. The planes of the portions of the respective straps which are intermediate their edges intersect each other as clearly shown in Fig. 5.

I prefer to conceal the securing devices 16, 17, as shown, by causing the hinge straps to extend thereover. The fasteners 22 are likewise concealed from view by being disposed at the inner face or surface of the retaining strips.

It is obvious that the retaining strips and their seats or grooves may have any desired cooperating shape in cross section, or, if desired, and as shown in Fig. 8, the grooves or seats may be entirely dispensed with and plain flat retaining strips 23 employed.

Any suitable material adapted for the purpose may be employed for the hinge straps, such as cloth, linen, muslin, leather or other flexible material of suflicient strength.

With a hinge structure such as described the screen sections'may be folded or angularly displaced relatively to each other in either direction from alined relation with equal facility.

'WhileI have shown and described a hinge joint structure embodying my invention as applied to screen sections it isapparent that the same may with equal facility be applied to doors, shutters, or other foldable devices.

From the foregoing description it will be seen that I provide an exceedingly simple, neat, eflicient, and economical hinge structure wherein the securing parts are concealed; It will also be seen that in the case where the securing screws 16, 17, are applied'at uncovered portions of the retaining strips the parts composing the hinge structure are readily and easily detachable with out injury. 7

Having now set forth the objects and nature of my invention, and a construction embodying the principles thereof, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent, is

1. The combination with adjacent relativelyswingmg members arranged edge to edge, of hinge straps connected to diagonally opposite points of said members the intermediate portions thereof passing between the opposed edges of said members, and retaining strips to secure said straps to their respectively adjacent members. 7

2. The combination with adjacent relatively swinging members arranged edge to edge, and having longitudinal grooves in 7 their opposed edge surfaces, of hinge straps having their respective edges extending into one side of the groove in one of said members and the opposite side of the groove in the other of said members, and means to secure said strap edges in said grooves.

Copies of this patent may be obtained for five cents each, by addressing the 3. The combination with adjacent relatively swinging members arranged edge to edge, and having longitudinal grooves in their opposed edge surfaces, of hinge straps having their respective edges extending into one sideof the groove in one of said members and the opposite side of the groove in the other of said members, and retaining strips fitted into said grooves to clamp the strap edges therein.

FL. The combination with adjacent relatively swinging members arranged edge to edge and having longitudinal V-shapcd grooves in their opposed edge surfaces, of correspondingly shaped retaining strips secured in said grooves, and hinge straps having their respective edges secured and clamped in said grooves by said strips, respectively, the portions of said straps intermediate their edges extending across and between the outer surfaces of said strips.

5. The combination with adjacent rela tively swinging members arranged edge to edge and having longitudinal V shaped grooves in their opposed edge surfaces, of correspondingly shaped retaining strips secured in said grooves, and hinge straps having their respective edges secured and clamped in said grooves by said strips, respectively, the portions of said straps intermediate their edge extending across and between the outer surfaces of said strips, corresponding edges of adjacent hinge straps being secured at opposite side of the same member.

In testimony whereof I have hereunto set my hand in the presence of the subscribing witnesses, on this 10 day of May A. D. 1916.
